Themes
Pick a visual theme and customize it to match your brand.
Overview
So a theme controls the visual feel of your entire quiz, the colors, fonts, button shapes, background styles, all of it. And Custom One comes with a library of over twenty ready-made themes organized by style: light, dark, industry-specific, fun, professional.
Walkthrough
To use one, open any funnel, head to the design panel, and click Themes. You'll see the library, hover any theme to see a preview, click to apply it. And the whole quiz updates live, questions, result page, end page, everything at once.
And if you've picked one but want to tweak it, you can. Every theme lets you override the primary and secondary colors, so you can match your brand hex codes exactly, the fonts for headings and body text, border radius for sharp or rounded corners, and button styling.
Changes apply instantly. And um, definitely switch to the mobile preview to make sure it still looks right on a phone, because most of your visitors will be on one.
Wrap up
One rule of thumb though, pick a theme that's close to what you want, tweak the colors, and stop. Don't try to build a theme from scratch if you can help it. Time spent on pixel-perfect design is time not spent on better questions.
